The EOC16 collets according to DIN ISO 10897 (DIN 6388) are designed for clamping cylindrical tools in applications requiring a high combination of clamping force, rigidity, and geometric precision. The low taper design combined with an extended clamping surface ensures highly efficient torque transmission, significantly reducing elastic deformation, vibration, and clamping play during machining.

These collets are particularly suitable for heavy-duty milling and high-load machining processes, where system rigidity directly affects surface finish quality and dimensional accuracy. The 6+6 bilateral slot configuration ensures uniform clamping force distribution, improving concentricity and minimizing form and geometry errors.

With a runout accuracy of ≤ 0.008 mm, the EOC16 collets provide precise control of radial deviation, which is essential for precision machining and quality control operations. The clamping range allows up to 0.5 mm below the nominal diameter, ensuring operational flexibility while maintaining high stability and safety.

The surface finish with roughness Rz 1.6 improves the contact between the collet and the tool shank, optimizing pressure distribution and reducing the risk of slippage even under demanding working conditions.

EOC16 collets are widely used in automotive, precision engineering, industrial manufacturing, and maintenance environments, making them ideal for CNC operators, engineers, and machine tool builders requiring high performance in heavy machining applications.
